I wonder about the practicalities of being a foreign monk in Asia, especially Theravada-majority countries.
It's more difficult to become a foreigner, than to stay at home in one's homeland. One could easily just stay at home.
About the Visa arrangements, can this at all be handled without much stress by one who doesn't use money?
How could one handle something requiring money, if not accepting, using or telling others to use and abstains from trade with householders?
In other words, if you need to get something done that requires money, then you need to deal with money, whether directly or indirectly.
What about the rule of not driving a car or using vehicles, is this a rule that can be kept by one in such a predicament?
It would be not wrong if sick and not able to walk to accept a male ride (cyclo, bike, cart, man-powered). It's also not wrong to give a fellow a hand cart ride, if given to use one and desire to 'drive'.
Anything relevant is of interest.
